Kharijah bin Zayd (may Allah have mercy on him) narrates that he heard Sayyiduna Zayd bin Thabit (may Allah be pleased with him) say: "The verse 'And whoever kills a believer intentionally, his recompense is Hell, abiding therein forever' was revealed six months after the verse of Surah al-Furqan: 'And those who do not invoke another god along with Allah, and do not kill the soul which Allah has forbidden except by right'."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Hammad bin Zayd except Muslim bin Ibrahim."
